For example, a curve algorithm function is constructed, and the obtained coordinates are substituted into the function, so that a curve can be drawn.
And the stretching submodule is used for stretching the spline curve according to the parameters of the building component to generate the building component.
The stretching submodule may stretch the line into a surface, and stretch the surface into a solid figure, thereby completing the modeling. The stretching submodule can stretch along a straight line or a curve to finish a three-dimensional geometric modeling based on parametric driving. Wherein the parameters required for stretching can be obtained from the parameters of the building element.
